User Manual

Advanced RF Technologies, Inc.

 Channel Center Frequency: The user can input the center frequency of the pass-band.

 Bandwidth: Allows the user to select the desired bandwidth for the passband. Choices for wideband

frequencies include 3, 5, or 10 MHz. Narrowband choices include 6.25, 12.5, 25.0, 75.0 and 200 kHz.

The required frequency spacing between channels is 4x the bandwidth from center to center. For

example, if there are 2 channels each at 12.5KHz, then the required frequency spacing between these

2 channels will be 50KHz (measuring from center to center). If channel bandwidths are different

between the 2 channels, then the required frequency spacing will be 4x the larger bandwidth.

 Downlink Gain: Minor gain adjustments can be performed on a per channel basis to equalize signal

levels

 Downlink Freq - Start: Displays the start frequency of the pass-band once the band selection has been

set

 Downlink Freq - End: Displays the end frequency of the pass-band once the band selection has been

set
